Right, it's this last part that's critical here. Directory authorities that do their own "bandwidth authority" measurements use their bwauth numbers rather than the self-reported numbers in the relay descriptor, for deciding whether to assign flags.
If you go to the very bottom of https://consensus-health.torproject.org/#relayinfo and put in this relay nickname or fingerprint, you'll see that 4 directory authorities -- the ones not running bandwidth authorities -- look at the self-reported number, and give the relay the Fast flag. But 5 of them, which are running bwauths, use their own numbers, which put the relay below the threshold. And since 5 is a majority of 9, their choice wins.
Hope that makes sense, --Roger
